Troubleshooting
Grape Ivy problems — and how to fix them
Grape Ivy (Cissus rhombifolia) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
White powdery patches with distorted, yellowing leaves; this plant is notably mildew-prone, so favour good airflow, keep foliage dry and avoid crowding.
Brown, crunchy leaves and stem dieback
Usually a sign of overwatering or root rot; remove dead growth and let the soil dry thoroughly before watering again.
Leaf drop
Often triggered by cold draughts, sudden temperature swings, or soil that is kept too wet or too dry; stabilise its position and watering.
Spider mites
Fine webbing and stippled, yellowing leaves, especially in dry air; rinse the plant and treat with insecticidal soap or neem oil.
Leggy, sparse growth
Long bare stems with few leaves indicate too little light; move to a brighter spot and pinch the tips to encourage bushiness.
